3. From the left side (viewed from the back) of the four-space
AAP opening in the HSA 400 front panel, remove the
L-bracket and mounting nuts.
4. Insert the SPA 12 speaker and front grill into the four-space
opening of the HSA 400.
5. Attach and tighten #4-40 nuts to the furthermost left
(viewed from the back) pair of threaded standoffs of the
SPA 12. This should seal the SPA 12 speaker onto the HSA
400 front plate.
6. Attach the speaker wire pair ends to the SPA 12 speaker by
soldering the exposed tips to the speaker’s positive and
negative terminal pair (marked – and +).
7. Place the L-bracket back in its original location, but do not
reattach the mounting nuts
.
8. Attach the rear enclosure. When doing so, keep the
following in mind:
• Ensure that the arrows on the labels affixed to each
piece are aligned and pointing upward before
covering the magnet cap with the rear enclosure.
• The bolt from the magnet cover should emerge
through the hole of the rear enclosure.
• On the left of the face plate, the rear enclosure covers
the threaded standoffs of the SPA 12 (i.e., they are not
visible). Conversely, the HSA 400 threaded standoffs
fit onto the holes of the rear enclosure and are visible
through them.
• On the right of the face plate, the rear enclosure
should line up with the pair of SPA 12 threaded
standoffs that emerge through the HSA 400 front
panel.
9. Tighten the lock nut and washer to the magnet cap bolt
that emerges from the rear enclosure.
10 . Tighten #4-40 nuts to the SPA 12 threaded standoffs on the
right side (viewed from the back).
11. Attach the opposite end of the speaker wire to the output
of your amplifier.
